Klavatuur

Klavatuur is the Dutch term for the keyboard of a keyboard instrument, encompassing the set of keys and the mechanical action that translates a key press into sound. It serves as the primary control interface between the performer and the instrument, and its design varies across instrument families. The best-known example is the piano keyboard, typically consisting of 88 keys arranged in repeating octaves; pressing a key activates a complex action that drives hammers to strike strings in the piano. In harpsichords and clavichords, the keyboard operates jacks with a plucking plectrum or a tangent that strikes the string, producing different kinds of tone.

Components and function: the klavatuur includes the keys, the keybed or support, and the action that connects key movement to sound production. In pianos, the action transfers motion to hammers; in harpsichords and clavichords, it operates mechanisms that pluck or strike strings. In pipe organs, a key press opens a valve that allows wind into a rank of pipes. The layout typically features white keys for the natural notes and black keys for sharps and flats, arranged in octaves.

Etymology and usage: the term klavatuur derives from related words such as clavier in French and Klaviatur in German, reflecting a shared concept of the keyboard as the instrument’s interface. In addition to traditional acoustic instruments, the term is also used for digital keyboards and MIDI controllers, where keys trigger electronic sounds rather than direct acoustic production.
